Anti-proliferative effect of chalcone derivatives through inactivation of NF-κB in human cancer cells
摘要:
To investigate the anti-proliferative effect of NF-kappa B inhibitor, a series of analogs of (E)-1-(2-hydroxy-6-(isopentyloxy)phenyl)-3-(4-hydroxyphenyl)prop-2-en-1-one (5a) were prepared and evaluated for their NE-kappa B inhibition and anti-proliferative activity against various human cancer cell lines. Compounds (E)-1-(2-(3,3-dimethylbutoxy)-6-hydroxyphenyl)-3-(4-hydroxyphenyl)prop-2-en-1-one (5e) and (E)-4-(3-(2-(3,3-dimethylbutoxy)-6-hydroxyphenyl)-3-oxoprop-1-enyl)benzenesulfonamide (5p) showed good NF-kappa B inhibition as well as potent anti-proliferative activity. SAR studies showed that all the compounds with potent or moderate NF-kappa B inhibition displayed good anti-proliferative activity. All the analogs (5b-r) maintained a good correlation between their NE-kappa B inhibition and anti-proliferative activity though the extent is not directly proportional to each other.

The present invention provides novel analogues of epicatechin and related polyphenols, their variously functionalized derivatives, process for preparation of the same, composition comprising these compounds and their method of use.
o-hydroxyacetophenones with 2 equivalents of arylaldehydes provides 2-aryl-3-(arylmethyl)chromones (a chimera of flavone and homoisoflavanone) in MeOH at 50 °C under mild conditions. The uses of various bases and solvents are investigated for one-pot facile and efficient transformation. A plausible mechanism is proposed.

A series of 2-amino-3-cyano-4-alkyl-6-(2-hydroxyphenyl)pyridine derivatives was synthesized and evaluated as IkappaB kinase beta (IKK-beta) inhibitors. Modification of a novel IKK-beta inhibitor 1 (IKK-beta IC50 = 1500 nM, Cell IC50 = 8000 nM) at the 4-phenyl ring and 6-phenol group on the pyridine core ring resulted in a marked increased in biological activities. An optimized compound, 2-amino-6-[2-(cyclopropylmethoxy)-6-hydroxyphenyl]-4-piperidin-4-yl nicotinonitrile, exhibited excellent in vitro profiles (IKK-beta IC50 = 8.5 nM, Cell IC50 = 60 nM) and a strong oral efficacy in in vivo anti-inflammatory assays (significant effects at 1 mg/kg, po in arachidonic acid-induced ear edema model in mice).

A family of compounds which function as selective ligands for the serotonin receptor 2B (5-HT
2B
) is identified. Some of the compounds are synthetic non-natural ligands which have a relatively strong interaction with 5-HT2B compared to naturally occurring compounds (some of which are identified for the first time herein as ligands for 5-HT
2B
). Because the compounds, both naturally occurring and synthetically produced, function as ligands for 5-HT
2B
they will have application in, for example, the treatment and/or prevention of nervous system disorders such as Alzheimer's disease.
